Many of today's smartphones sport very capable cameras, but unless you add funky lens attachments like the HiLO or a helpful device like the Spinpod, the recorded image is probably going to be either front or back. Chinese manufacturer Oppo revealed a new smartphone at a press conference in Beijing on Monday that kind of combines both ideas on the device itself. The N1 features a hinged camera module capable of rotating 206 degrees for front, back, top or angled photography.

Zoom has announced a smaller brother to the company's excellent Q3HD handycam.

As well as helping ensure that mobile photographers are able to grab all the action by minimizing shutter lag between shots, the new sensor also caters for in-device image editing and high dynamic range photography.

While 1080p has barely had time to establish itself as the standard for high definition video in the home, its replacement is already making its presence felt. Panasonic provided a glimpse of our ultra high resolution future with its 152-inch 4K resolution plasma TV at CES in 2010, but now Sony has become the first company to release a 4K home cinema projector that offers four times the resolution of existing 1080p displays.

Whether you're speeding down the slopes, on a biking epic through the woods or riding the rapids in a kayak, having to wait until you get to a laptop to share your recorded adventures with friends and family is nothing short of inconvenient.

The camera does this by wirelessly connecting with a smartphone or tablet running the company's free-to-download app, although users will need to buy an extra bit of kit to make all this possible.
